Abstract
A linear peristaltic type pump capable of moving high viscosity material without creating an appreciable amount of heat includes a flexible conduit that is progressively compressed by a series of gear-driven compressing shoes that move linearly into and out of contact with the conduit by reciprocating motion, with a dwell time provided for each conduit compression event. A specific gear and linkage drive system is provided, including interengaged gears driving the compressing shoes via links on either side of the shoes.
